Fastenings of the ltype above referred to are particularly adapted for fastening wall or ceiling boards to metal studs, joists and other im structural supports, and they are designed to fasten edge-to-edge adjoining boards at a definite distance from an edge of the supportV or/and to secure boards lying iush with an edge of the support. l y

In the use of fastenings of the construction disclosed in the aforementioned application for patent, it was necessary to supply fastenings of different proportions to accommodate joists or other supports of different widths and it is the object of the present invention to provide a fastening that may beadjusted to supportsof dierent widths throughthe medium of a detachable link associated with one Vor two of the members of thefastening in which its distinctive features are embodied.

Further objects of the invention reside in details of construction and novel arrangements of part-sas will fully -appear in the course of the following description.

Figurell, a face-view of the construe tion'shown in Figure 10; and i i Figure 1'2,a sectional elevationshowing a'clip of modified construction in connection with a joist of angle-section.

Like characters of reference designate correspondingparts throughout the views.

The'fastening which is of the nature of a bendable clip, consists in the construction illustrated in Figure 1, of two end members V5v andan interposed connecting link-member 6. i i 1 Each of the end members comprises two plates 7 and 8, bent at right angles to each from the yoke at substantially right angles thereto.

The plate 7 has a U-shaped cut 21 forming al yoke 13 and a iiange 12 which may be bent at right angles to the yoke 13 inthe plane ofthe plate 8. The yoke has acrosspiece 13a at the end of the plate 7 `for the application of a link hereinafter to be described.

i The flange 10 is' split as at 14, to provide tongues 15 which in practice are bent along a line 16 thatzmay bevdefned by perforations or `other weakening means, and the a-nge-12 has a similar row .of perforations 17 defining a tongue 18. v

In the construction disclosed in the above mentioned application for patent, the two members were integrally connectedby a body member of which the plates 7 of the new constructionfwere integra-l parts and the clips could therefore be applied only to supports whose width corresponded tc the length of the body member.

In the present invention the .distance between the parallel plates 8 of the fastening may be varied by the provision of ya detachable connecting link.

In the construction illustrated in Figure l, the connecting link consists of a strap 19 of bendable metal, the ends 2O of which are bent at right angles to the body portion, to engage across the cross pieces 13a of the yokes 13, of the plates 7 of the end members. Y

After the ends of the link have been inserted in the openings of the yokes, as shown, they are bent around the cross pieces of the same upon the surface of the plate, as shown in 'Figures 5 and 6.

Figures 3 and 4 show as a variation of the link construction, a link composed of a strap 22 provided with .Teheads 23. The width of the heads is slightly less than the length 'ofthe openings in which they are to be in# serted, and the link is applied by first passing its heads through the openings of the plates Vof the end members of the clip, and then turning the link through 4an angle of 90'degrees whereby to position the heads in contact with the-cross pieces of the yokes 13, as shown.

It will be apparent that in the construction illust-rated in 'Figure 1, the distance between the end members of the clip may be varied by bending the link at different distances from its ends and that in both illustrated forms'of the invention the distance betweenthe end members may be adjusted by the provision of links of different lengthsf `The method of using the clip illustrated in Figure l has been shown in Figures 5 and 6, in which the reference character 25 designates a joist, stud or other structural support made of flanged metal, and 24ethe wall or ceiling boards fastened to the support by means of clips ofthe present construction. 1

The support has been shown as made of channel section and in Figure 5 the boards have been shown as meeting at a distance from an edge of the support.

The plates 7 of the end-members of the clip, c'onnected'by the link 6, lie flat against the body-plate 25 of the support, the. plates 8 lie flat upon the flanges 26 of the supportV and the yokes 9 are. bent around the edges of the flanges. Y

The' flanges '10' of the end-members extend outwardly from the flanges of the support and at right angles thereto, and after the boards 24 have been placed against the flanges 26g-at opposite sides thereof, the tongues 15 of the flanges l0 are bent upon the outer surfaces of the boards Yto -secure Vthem in place. The weakened bending lines of the flanges are at a distance from the plates of which, the

flanges are a part, slightly less than the average thickness of wall or ceiling boards so that when the tongues are bent upon the boards they may be pressed into the material of which the boards are composed so as to lie flush with the outer surfaces of the same. Thus the clips maybe completely concealed by a filler or filler-strips used in finishing the structure of which the boards are a part. The application of the tongues in this manner furthermore draws the boards tightly against the flanges of the support, and firmly secures the boards to the support and in mutual alinement. Y i Y The flanges 12 of the clip extending in the planes of the respective plates 8, provide an additional support for the boards at one side of the joist.

In the method of application illustrated in FigureG, the wall or ceiling boards 24 extend to an edge of the surfaces of the support, against which they rest as frequently occurs in places where an adjoining board 27 lies flush against the face of the body plate of the support. Y In this case, the flanges 10 of the clip are bentfinto the planes of the yokes 9 and the flanges 12 are bent at right 'angles to the plate 8 of which the yokes are a part, to engage with the adjoining edges 'of the boards; The tongues 18 of the flanges 12 are bent upon the outer surfaces of the boards 24 and the latter are thereby fastened in place, as before.

It will be apparent that the clips or fasten'- ings may be employed atthe will of the'user, to fasten wall or ceiling boards in different positions relative to the joists or studs against which they are placed,by theprovision of the two flanges on each end-member, which by their tongues are adapted to embracethe` edges of the boards as shown and described.

The clips may be made of any suitable bendable metal and they may, if necessary, be coated with a rust-proof material.

In certain instances, the clip may be composed in its entirety of one member of' the construction of the end-members of the'lirst -described construction, and a link-member of suitable length.

Referring to Figures 7 and 8 of the drawings, a clip of this character has been shown .as applied to fasten ceiling boards 24' disposed at one side only of a joist 25 of anglesection: A link 28 similar to the link. 19 but of greater length, is bent around the flange of the joist opposite to that engaged by the ceiling boards. Theopposite end of the link is hooked across the cross piece 13ak of the plate 7 of a member 5 similar to the endmembers hereinbefore described, and the yoke .9 of the member is bent around the other flange of the joist.

The tongues 15 of the flange 10 are pressed into engagement with the outer surfaces of the ceiling boards 24 as before, and the flange 12 lies flat against the opposite surface of one of the boards. rlhis method of application is of particular value for fastening ceiling boards that are disposed at one side of the joists only.

It is preferred to bend one end of the link or strap 28 before application, as shown in Figure 9, and to bend the other end of the same around the flange of the joist at the required distance.

In Figures 10 and 11, has been shown the method of fastening wall boards to a joist 29 of angle section. y

The link 28 bent across the two sides of the angle-joist are hooked around the crosspieces 9c and 13a of the yokes 9 and 13 of the member 5. The tongues 15 of the flange 10 disposed between the wall boards, are bent in opposite directions upon the outer faces of the same and the flange 12 extends along the opposite side of one of the boards.

Figure 12 illustrates a modification of the clip in connection with a joist of angle-section, the parts of the clip being similar .to those of Figures 10 and 11.

' The link 28 is bent across an edge of the joist and the member 5 is bent at one end across the opposite edge of the same and eX- tends across one side of the joistland partially across the other side of the same where it connects with the link. y

The. end of the link is, as before, bent across the cross piece 18a of the member.

It is to be notedthat the U-shaped cut and the flange bent outwardly therefrom have been omitted at one end of the member as being unessential.

What I claim and desire to secure by Letters Patent is:
